I prefer body weight exercises, essentially anything that does not need tools to be performed. Now, most of the 'literature' on how to gain strength is in terms of lifting weights. Is there some kind of chart that allows to translate weight lifted into body-weight exercise performed?
Also, the amount of information on this site is getting overwhelming, as is the content of the open threads. I have no suggestions on how to alleviate this.
You're going to want Building the Gymnastic Body, by the former gymnastics coach of the US national team IIRC. Keep in mind that to advance past a certain stage you will need to start weighting your dips and chin ups. But this can be accomplished in a variety of ways at home. A chin up bar and rings can be had for under $100, assuming you have a good spot for them.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
